As a practitioner and herbalist I am often asked whether it is best to take herbs as part of your meal or as a capsule. I am definitely in favor of using herbs and spices in food, for instance I seldom make anything without at least a little bit of Turmeric, but I also know that heating can destroy a lot of the constituents of herbs, especially the volatile essential oils.
As cited below, a study recently came out that actually tested this and found that just 10 minutes in a pressure cooker will remove about half the Curcumin out of Turmeric, 40% of the Capsaicin out of Red Pepper, and 30% of the Piperine out of Black Pepper; Curcumin, Capsaicin and Piperine being proved the main constituents that are responsible for a significant amount of the healing activity of the respective whole spice. And the loss was not significantly different whether or not there was other food in the pressure cooker.
This just confirms the need, given the choice for most herbs, to take them as whole, fresh and as raw as possible, and this will mean capsules for most people. Is it good to cook with Turmeric and other herbs and spices?
Absolutely. Is it good to also take whole Turmeric root in capsules on a daily basis? Absolutely, you want the Curcuminoids in your Turmeric. Just make sure your herbs are very potent and pure and are grown and processed in a responsible and fully sustainable context.
